When doing a RMAN DUPLICATE from backup connected to the target, how current does the duplicate make the database when no until time is set? The closest thing I can find in the documentation is the following statement:
Restores and copies the duplicate data files and recovers them with incremental backups and archived redo log files to a noncurrent point in time.
How current is this noncurrent point in time? Does it apply all the archive logs it has available to it at the start of the duplicate or perhaps available when it reaches the recovery part of the duplicate?
